Flue gas recovery system and device for carbon fiber crucible

Abstract

The invention discloses a flue gas recovery system and device for a carbon fiber crucible, and particularly relates to the field of flue gas recovery of carbon fibers. When the carbon fiber crucible is subjected to high-temperature treatment in the carbonization furnace, generated smoke dust can be liquefied into tar, when the motor is not started, the fan seals the smoke outlet channel and accelerates temperature rise in the carbonization furnace, and when the motor is started, the fan can push smoke to flow in an accelerated mode, and the smoke outlet of the smoke outlet pipe is inserted into the water surface in the dust remover at a certain inclination degree to form whirlpool; tar-shaped smoke dust in smoke can be cooled to be solid after encountering water, the water vortex can accelerate collection of the solid smoke dust to the bottom of the dust remover so that the solid smoke dust can be discharged and recycled through the dust discharging valve, a communicating pipe is connected to the position, lower than the liquid level, of the dust remover, and high-temperature water is guided into the air cooling pool through the communicating pipe to be subjected to air cooling; and the low-temperature water is injected into the dust remover through a water inlet pipe to form circulation. The flue gas after dust removal enters a desulfurization and denitrification device for desulfurization, denitrification and other purification, and then is discharged into the atmosphere.

Description

technical field [0001] The invention relates to the field of carbon fiber flue gas recovery, in particular to a carbon fiber crucible flue gas recovery system and a device thereof. Background technique [0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber containing more than 95% carbon. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber, and undergoing carbonization and graphitization. Carbon fiber is "soft on the outside and rigid on the inside", lighter than metal aluminum, but stronger than steel, and has the characteristics of corrosion resistance and high modulus. It is an important material in national defense and civilian applications. [0003] In the prior art, the prefabricated carbon fiber crucible needs to be placed in a carbonization furnace for high-temperature treatment. The smoke in the carbonization furnace is in ...
